Omnipositional Cable Suspension for Stable 3D Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension systems for inanimate objects lack the ability to maintain stability and repositioning flexibility without requiring significant changes in the suspension setup.
Innovation Solution
An omnipositional cable-suspension system using two spaced apart holes in the object, with two closed cable loops that can be hooked to variable hooking points, allowing for stable suspension and easy repositioning without altering the system, and optional motorized pulleys for precise orientation control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional suspension systems with fixed cable attachments are used, then the object can be suspended stably, but the system requires significant changes to reposition or reorient the object
Solution Approach 1:
The cable system is segmented into multiple independent loops, each capable of independent adjustment. The object has multiple holes through which different cable loops can pass, allowing selective engagement of different cable segments to achieve various positions and orientations without changing the entire suspension system.
Solution Approach 2:
The cable loops are designed to be dynamically adjustable rather than fixed. The loops can slide through the holes in the object and be repositioned along their length, enabling the object to be moved to different positions and orientations by simply adjusting the cable loop positions rather than reconfiguring the entire suspension system.
2Measurement precision
If multiple cables are used to control object position and orientation, then precise positioning is achieved, but the system becomes complex and difficult to operate
Solution Approach 1:
Each cable loop serves multiple functions: it can control the object's position in space, its orientation, and can be adjusted to achieve different configurations. The same simple loop structure can be used for various positioning tasks by changing which holes the loop passes through and where it is attached, eliminating the need for complex differential cable systems.
Solution Approach 2:
The system uses identical cable loop structures repeated multiple times rather than complex unique mechanisms for each degree of freedom. Each loop is a simple closed loop that can be attached to different hooking points and passed through different holes, creating a scalable and easy-to-operate system that achieves precise control through geometric configuration rather than complex mechanics.
3Adaptability or versatility
If the object needs to be repositioned frequently, then versatility is improved, but the suspension system requires frequent adjustments and changes
Solution Approach 1:
The cable loops are pre-formed as closed loops with attachment points ready for engagement. The holes in the object are pre-positioned to accommodate the loops. This preliminary preparation allows rapid repositioning by simply sliding the loops through different holes and attaching to different hooking points without requiring on-site fabrication or complex adjustment mechanisms.
Solution Approach 2:
The system is designed for dynamic reconfiguration where cable loops can be quickly moved between holes and hooking points. The loops maintain tension and stability in any position, allowing frequent repositioning without requiring the system to be taken apart or significantly reconfigured, thus minimizing time loss during repositioning operations.

AI summary
An omnipositional cable-suspension system suspends an inanimate object. A pair of spaced apart holes pass through the object. A first closed cable loop passes through both of the holes and a first hooking point, so that a first cable is movable within the holes. A second closed cable loop passes through both of these holes and to a second hooking point, so that the second cable is also movable within the holes. The inanimate object can be moved from one position to another, while the object remains stable in any position so placed. This omnipositional cable-suspension system enables the suspension of any inanimate object (the “object”) that can be readily moved to any position about its three-dimensional axis without changing the cable-suspension system of the object. The object can be repositioned to any other stationary position as many times as desired.
